Only few traits I chose regularly - loner (in all casual games), neurotic or insane depending on Sim, perfectionist or neat, brave and adventurer, ambitious and OE. Savvy Sculptor only in dynasty for sculptors. I recently started to love Evil trait, as they got that positive moodlet even when they are suffering, and eco friendly got a couple of very nice additions (such are Replenishing the Earth from gardening, or Saving the water or something after shower)
